AIX: abrupt node eviction

(Doc ID 2111627.1)

Last updated on JULY 06, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.1 and later
IBM AIX on POWER Systems (64-bit)

Symptoms

One of the cluster node is getting evicted and restarting abruptly.

Commonly, the abrupt node eviction is due to heavy paging or memory starvation that leads to some threads of ocssd.bin not getting scheduled.

However, the server shows that a large amount of memory was free at the time of node crash.
